Other MW Technologies


Bluetooth also transmits in the microwave region but is a weaker signal than a mobile phone, WiFi router, etc., and has a short range, e.i., 5 – 30 metres.  Generally not thought to be a problem relatively speaking in comparison to the other microwave communication technologies out there. Nevertheless, wearing of a Bluetooth over the ear on a continual basis is questionable.

Broadband over Power Lines (BPL)

Broadband over power lines (BPL) is a method of power line communication that allows relatively high-speed digital data transmission over the public electric power distribution wiring. The technology allows the higher frequency data of the internet to be carried on top of the power voltage signal. A BPL modem is used to couple and decouple the internet signal from the power line.

BPL is a technology for the Smart grid.  It may be used to transmit data from household appliances to the power company directly.

Since the conductor used in BPL is a power line, it is unshielded to contain high frequencies.  This means there is little in the way of the signal from radiating into the surroundings.  This means there is a high signal loss with distance along the cable.  (However, BPL form the start was thought of as a something midway between an internet cable and a wireless system, and so not that much emphasis was put the wire conductor.  (In a way one should think of the wire power conductor as a pathway of high conduction, a shortcut to propagating through space, or the air).

The end result is that there is microwave radiation running along the power line and mains of your home or business.  Each socket becomes an access point for the internet.  Wherever the wiring in the house goes, there goes a surrounding microwave field.

BPL also is a contributor to dirty electricity.


Wind Turbines

Wind turbines can also contribute as a source of ‘dirty electricity’: http://www.cellphonetaskforce.org/?page_id=220
